Homemade FM Transmitter / DIY nadajnik FM

The movie presents my homemade mp3 transmitter (mono) with jack connector instead of microphone. Sound quality is quite well, if you're not an audiophile you won't get mad ;) It's powered by 9V battery. Operation range is about 10-15m at home and about 40-50 meters in free space (with ~15cm wire antenna). Nokia 6230i as radio receiver :) Mp3: Creative MuVo V100
Na filmiku przedstawiam mój domowej roboty nadajnik FM mono (z jack'iem zamiast mikrofonu). Jakość jest całkiem niezła, jesli nie jesteś audiofilem nie wkurza ;) Zasilanie ze zwykłej baterii 9V. Zasięg w budynku ok 10-15m, w otwartej przestrzeni 40-50m (z antenką z drutu, ok. 15 cm). Jako odbiornik Nokia 6230i :) MP3 to Creative MuVo V100

Hi bro, very interesting video, I am new to electronics and i'm interested in building one of these so i can use it during school.. To increase the range of the signal to about 1-2km what other things do i need? a 1metre antenna?

@BkkCheesepie: This transmitter is based on only one transistor, so there is no easy way to increase its range. If you want something stronger try searching google for "2w fm transmitter". You are new to electronics, so I think it's a bad idea for you to make something such strong - it's really hard to make it work properly and in most of countries it's illegal to use it.

pokaz jak to zrobić

[PirateRadioPoland]

Zaekranuj całość i dodaj separator na dwóch tranzystorach (BF245 i BF240) - nie będzie tak bardzo odstrajał się przy dotknięciu anteny czy zbliżeniu ręki. Jakość dźwięku też się prawdopodobnie poprawi :)

Możesz podać schemat, albo chociaż link, nazwę?

Hi, I want a design of rf radio to be used in rc toys. The idea is to get off the shelf design and manufacture it. The requirements are

1] It should cost cheap

2] It should have atleast 4 channels

3] power requirement is not an issue

4] might add knowing more in deep :) I am not from electronics field and I am a mechanical eng.

Can you guide or design it?.Any cost figures for the work?
